The LM317MDCYR from ST is an adjustable floating positive voltage regulator designed for applications requiring a stable output voltage. It can supply an output current of up to 500mA over an adjustable output voltage range of 1.25V to 37V. This regulator requires only two external resistors to set the output voltage, simplifying circuit design.
Key electrical characteristics include a typical line regulation of 0.01% and a typical load regulation of 0.1%. The device incorporates built-in features such as short-circuit current limiting and thermal overload protection, enhancing its robustness. It is stable without requiring an output capacitor.
The LM317MDCYR is housed in a 4-pin SOT-223 surface-mount package. It operates within a junction temperature range of -40°C to +125°C. The typical thermal resistance for the SOT-223 package is 77.7°C/W.
This component is suitable for various power management tasks where adjustable voltage regulation is needed. Its features make it a reliable choice for designs requiring moderate current and precise voltage control.
